An alcoholic beverage and or container of hard liquor purchased sometimes days, but usually only hours before going to a bar, or going bar or club hopping. This alcohol is drank before going out, and sometimes drank while out, out of a flask, in the act of saving money on the bar tab but still keeping your buzz up.

Some people even associate this coupon with the act of pregaming. Pretty much anything dranken while pregaming to any event could be considered a coupon.

To be a 'Coupon', or to use 'Coupon Methods' is to effectively take advantage of your surroundings in order to enhance ones own private needs.

Believed to be derived jointly from the prevalence of coupons in late post-industrial/capitalist society (largely exchangeable for low-quality goos - see coupoff) and from the Scots/Irish/Gaelic 'coupon' meaning face - coupon/face then suggesting head or oral.
